Connectivity in Cambodia
Our Cambodia eSIM connects to Smart and Metfone, the two networks with the widest reach across the country. You get fast LTE and growing 5G in Phnom Penh, Siem Reap near the Angkor temples, and the coast around Sihanoukville. Coverage stays reliable along the main national highways and in provincial towns like Battambang and Kampot, then softens in the Cardamom Mountains and the more remote stretches of the northeast.
If you are heading to the islands, plan around the signal. Koh Rong and Koh Rong Samloem have usable data near the main piers and beach bars, but it thins out on the quieter coves and can drop on the boat ride over. The same pattern shows up around Angkor, where you will hold a strong signal at Angkor Wat itself but hit weaker patches among the outlying temples like Beng Mealea.
The eSIM attaches to the local network as soon as you land, so you can get online at Phnom Penh or Siem Reap airport before you reach the customs hall. Because this is a data roaming plan, your traffic may route through a gateway outside Cambodia, so a few sites or apps might occasionally treat you as browsing from another country. For maps, messaging and booking a tuk-tuk it makes no practical difference.

Cambodia eSIM FAQs
Which networks does the Cambodia eSIM use, and where does it work best?＋−
It runs on Smart and Metfone, so you get solid coverage in Phnom Penh, Siem Reap and Sihanoukville, along the main highways and across most provincial towns. Signal weakens in the Cardamom Mountains, parts of the northeast and on the outer edges of the islands.
Can I make calls or send texts on this eSIM?＋−
No, this is a data-only plan with no phone number, so it cannot send or receive SMS or regular calls. Keep your normal SIM active for bank OTP codes and calls, while WhatsApp, FaceTime and similar apps keep working over the data on your existing number.
Can I top up if I run low on data?＋−
Standard plans can be topped up with more data before or after they run out. Unlimited plans cannot be extended, so once one ends you simply buy a fresh plan.
Will the eSIM work on Koh Rong and around the Angkor temples?＋−
Yes, though with gaps. You will have data near the main beaches, piers and Angkor Wat itself, but expect it to thin out on the quieter island coves, the boat crossings and the more remote temples like Beng Mealea.
